I’ve got a stock dual mass flywheel if anyone is looking. I lucked into a autech for my build.

Wish I could find a damn s15 autech sr20de engine.

Hey! What’s the exact fluid capacity on the 6mt? And can you pour it in from the shifter like the 5mt?

*TheRealSy90* · 10-30-2017, 11:14 PM

Should be the same capacity as the 5sp and yes.

Pull the side "fill" plug and add fluid until it starts to drip/pour from that hole.

I would imagine it's probably slightly less considering there is more gearing/shafts/bearings in the same space.

6MT oil capacity is 1.8 liters (3-7/8 US PINT)

[QUOTE=Fastimport;6235312]Does anyone know what these weigh?/QUOTE]

OK, this thing weighs 92.6 lbs without throw-out assembly, for inquiring minds.

The one I picked up off Yahoo-JP turned out to be an HPI close ratio.

And since it is good for 430HP, it's going into my Cressida.

I'll pick up another for my old Datsun L4.

Goldhawg · 11-16-2017, 04:54 AM

Anybody have a part number for the slip yoke? I didn't get one with my tranny and need one and I was told it would be the same as the automatic 240SX but can't find a part number online.

Fastimport · 12-03-2017, 01:34 PM

Although the speed sensor port wasn't bored into the tail shaft housing, when I pulled it apart, there was a nice surprise

A genuine 6-speed drive gear was already on the shaft !

Now, if I can just find the part number...

The housing was bored, and because this is going into a cable drive application, I picked up the driven assembly from the old Z-car 71B trans.

*TheRealSy90* · 12-03-2017, 02:56 PM

Woah, first 6sp I’ve ever seen with a speedo gear from factory.

Another local Nissan guy thinks that it's aftermarket, and is digging for the info.
I'll let you know.

99lspwr · 12-07-2017, 09:15 PM

anyone know the part number to just the cross member? I have an s14 with this 6 speed and only 2 of the cross member bolts are currently being used...

Looks like you can buy an installation kit that includes that cross member. Start there maybe? https://conceptzperformance.com/nism...et_p_24222.php

thats the one i was coming across as well... Just did not need all that stuff in the kit since my car is allready together and running.. Thanks for the reply

Fastimport · 12-12-2017, 08:22 AM

I have 4 of the speedo gears coming from Japan (all that I could find).
And will be offering them as a kit, that will include boring the tail shaft housing, the gear, ball, and 2 snap rings.

Stay tuned

Add me on your list for s14 speedo.

*TheRealSy90* · 12-12-2017, 08:54 AM

So what's the deal on the speedo gears? They're oem? And there's only 4 left in the world or they just don't have many in stock.

All I care is he’s doing us a favor. I don’t have time to sit and search.

jdm_land · 09-27-2018, 08:26 AM

Does anyone know if the S15 auto driveshaft will work with the 6 speed in a s13 with a skyline diff? Thank you

slow_sr20 · 01-07-2019, 07:08 PM

Anyone running short shifters on their 6 speed? I’m looking for input. I never ran short shifter on my 5 speed SR but the six speed throw seems very long?

I’ve only ever seen one C’s That I slept on...
There’s an Australian company (Cube) on EBay that has a nice looking one, and anther on EBay that appears to be a copy of cube Australia.

I’m not super aggressive and I understand short shifters can be hard on synchros, still would like to see what others are doing.

I have a genuine c's for 6 speed available. PM me

*TheRealSy90* · 01-07-2019, 10:59 PM

At this point it just seems so much easier to run an abs ring and dakota converter for the speedo.

zenkizenki · 09-09-2019, 06:22 PM

My 6 Speed is about to blow, can i use the 6 speed bell housing on a ka24de tranny? Keep the dual mass flywheel or go with smaller 5 speed one.
Thanks
